i'm sorry about your mother, it really does hurt when they do that. it's almost like some of them see their children as a personal investment on the same level as a hunting dog or track horse... my mother definitely placed all of her own past regrets and ambitions on me, trying to raise me to become what she couldn't. i was supposed to grow up to become a perfect sheltered princess, not my actual true self.
whenever the time comes for me to start transitioning, i won't bother taking her with me on the journey. she once said something that made me give up on her completely. admitted that she's bad at communicating with introverted people, so she never even tried to get to know me as a child. and probably doesn't really care to know me now either. she just wants me to be the person she wants me to be, and still says she wants the best for me when she insists on me abstaining from any of the things that might actually make me happy.
kind of lost all respect for her as a mother. she can be a great person to have around, really good with practical things.
she just isn't a mother to me, only the person who gave birth to me and provided for me in my early years. and for that she shall have my thanks.
but everything else just... lacks.
